6 Claims.

The present invention pertains to spinning spindles, and has more particular reference to such spindles wherein a spindle blade is revolubly mounted within an oil-containing spindle base 's which is fixed to a spindle rail.

Spindle bases of the type mentioned are usually z, cast in one piece and fitted to the spindle rail in a manner which permits the entire spindle to be adjusted bodily to properly align with other parts of the spinning frame. Such construction is objectionable, not only in that it is expensive to manufacture but also in that the aligning operation must be performed all over each time the spindle base is removed fo-r cleaning and re-inserted in the spindle rail.

It has been proposed to overcome the aforementioned objections by making the base of an outer member, which can be more or less permanently xed to the spindle rail, and one or more inner members which can be separately removed for cleaning. However, such proposed constructions have not been acceptable commercially, for various reasons, such as failure to provide for an adequate oil supply, or failure to provide means for preventing leakage of oil from the base.

Accordingly, it is a principal object of my invention to provide a two part spindle base comprised of an outer xed member and an inner removable member, which base shall be so constructed as to effectively prevent the escape of oil therefrom.

Other objects will become apparent as the description proceeds.

The preferred embodiment of my invention is illustrated on the accompanying drawing, of 35 which:

Fig. 1 is a View partly in section and partly in elevation of the complete spindle;

Fig. 2 is a detail of the outer member of the spindle base; and

Fig. 3 is a detail of the inner member of the spindle base. l

The spindle shown on the drawing includes a spindle blade I having a whorl 2 fixed thereto, the spindle blade being rotatable by means of a driving band (not shown) which engages the whorl. The spindle blade revolves within the base, to be described, being preferably mounted in a conventional bearing such as bolster 3. The bolster is removably positioned in the base and held from rotation therein by a key 4.

The spindle base according to the present in vention is constructed of two separate members. The hollow outer member 6 is generally tubular throughout its length, except that it is enlarged at its upper end. That is, the upper end of the member 6 is comprised of a larger tubular portion 1 connected to the main body of the member by an integral flange portion 8. The outer member is threaded externally as at 9 and a nut I0 en- 5 gaging the threads serves to fix the member to the spindle rail II. It is noted that the flange 8 rests on top of the spindle rail, and the hole in the rail through which the base passes is larger than the external diameter of the base. This conl struction, together with the packing commonly resorted to, permits the spindle to be aligned with other parts of the machine.

The hollow inner member I2 is generally tubular in form, except that its bottom end is closed l as at I3. This member extends entirely through the outer member 6, and extends upwardly into a recess I 4 formed in the whorl. The annular space between this member and the enlarged portion 'I constitutes an oil reservoir which may have any capacity reasonably to be desired.

An oil seal is provided between the inner and outer members below the reservoir, such seal being herein constituted by cooperating annular Shoulders I5 and I6 formed, respectively, on the 25 inner and outer base members. The inner member is provided with oil leads, as I'I, extending therethrough at the oil reservoir. This member, below the oil seal, is imperforate, wherefore it contains a quantity of oil from the oil reservoir.

The inner member I2 is removably secured to the outer member 6, the former being threaded externally as at I8, and the latter being threaded internally as at I9, for this purpose. The threads are preferably spaced some distance below the oil seal. The lower end of the inner member may be apertured as at 20 for the reception of a suitable tool (not shown) for screwing the member into and out of the outer member. It will be apparent that the spindle may be entirely dismantled, and the inner member detached from the outer member, without disturbing the adjustment of the latter in the spindle rail. Furthermore, such result is accomplished in a construction which provides ample oil capacity, and which, due to the fact that the parts can be manufactured on a screw machine, can be produced at a very low cost.

It is found that oil within the spindle base feeds up the blade,` over the top of the base and onto the walls of the recess I4, from whence it flows downwardly and is thrown by'centrifugal force from the lower edge of a sleeve 2|. This sleeve depends from the whorl exteriorly of the base above the oil reservoir. An oil-collecting member 22 is fitted into the oil reservoir and extends upwardly about said sleeve. The upper part of the oil-collecting member is of frusto-conical shape, whereby it collects the oil without causing it to be vaporized, the collected oil being kthereupon returned to the reservoir.

The oil-collecting member 22 and its relation to the sleeve 2l are disclosed and claimed in my patent application Serial No. 746,198, led of even date herewith.

Having fully disclosed the preferred embodiment of my invention, I claim:

1. A spindle base consisting of a hollow outer member adapted to be fixed in arspindle rail, a hollow, separately removable inner member extending entirely through said outer member concentrically therewith, said outer member being enlarged at its upper end to provide an annular space between the members which space constitutes an oil reservoir, and cooperating annular shoulders on said members providing an oil seal below said reservoir, said inner member being closed at its lower end and being providedv with oil leads above said oil seal.

2. A spindle base consisting of an outer member having a tubular lower portion and a` larger tubular upper portion comprising an oil reservoir, a hollow inner member extending through said outer member, cooperating annular shoulders on said members providingY an oil seal below said reservoir, said inner member being imperforate below said oil seal, and means detachably securing said inner member within said outer member. v

3. A spindle base consisting of an outer member adapted to be fixed to a spindle rail and an inner spindle supporting member extending entirely through said outer member, said outer member enlarged at its upper endeto provide an annular oil reservoir, cooperating annular shoulders on said members intermediate the ends thereof which shoulders provide an oil seal below said reservoir, said inner member being imperforate below said oil seal, and cooperating threads on said members for removably securing the inner member within the outer member.

4. A spindle base comprised of concentric inner and outer members spaced apart at the upper end of said outer member to provide an annular oil reservoir, cooperating shoulders on said members below said reservoir forming an oil seal, said inner member being imperforate below said oil seal, said members being threaded below said oil seal whereby the inner member is detachably secured to the outer member and means for xing said outer member to a spindle rail.

5. A spinning spindle comprised of a spindle blade having a whorl thereon, a bolster within which said spindle blade revolves, a hollow outer member having an oil reservoir at its upper end, a depending sleeve on said whorl, an oil-collecting member fitted within said reservoir and extending upwardly around said sleeve, an oil-containing inner member extending through said outer member and extending upwardly inside said sleeve, said bolster being positioned within said inner member, there being oil leads from said reservoir through said inner member, an oil seal between saidinner and outer members below said. reservoir, and means detachably securing said last mentioned members together.V

6. A spinning spindle comprised of a spindle blade having a whorl thereon, an oil-containing inner member within which said spindle blade revolves, said inner member extending upwardly into a recess formed in said whorl, a fixed outer member through which said inner member extends, said outer member at its upper end being spaced from said inner member to thereby form an annular oil reservoir, an oil collecting member extending from within said reservoir upwardly about the lower portion of said whorl, means below said reservoir forming an oil seal between said inner and outer members, and cooperating threads on said last mentioned members for detachably securing them together.
